I don't have an answer on dev mode. Dev mode isn't on my side but on Meta side. I can't really help you except showing you some tutorial videos...
got it, ill see then
Update: ive try to use a different phone number from another country..and i got the sms. I think is all about the vpn that stop the receiving of it. Just in case someone will have the same issue. That worked for me. All the best.
Okay, good to know ! Thanks !
Have fun with QGO !
